No reference to AS. I think you are talking about air speeds in excess of 60 MPH, and at 45 MPH this math doesn't hold up.The Cl max of a symmetrical airfoil with infinite aspect ratio is near18 degrees.
An aspect ratio of 4 increases this angle by about Cl / π. A (radians) i.e 4 degrees.
Turning a monobloc rudder beyond 22 degrees appears to me counter productive to stop a yaw.
